A type of silicone adhesive was used for bonding anti-irradiation cover glasses to space solar cells. A new adhesion process for solar cells was designed, and implemented by means of an automated coating and bonding system based on an industrial robot. On the basis of non-Newtonian fluid theory, flow models of three sub-processes were created, and the commercial finite element analysis code Adina was employed to simulate the whole process. The purpose of the investigation was to acknowledge the mechanism of the adhesion process and identify correlative factors that influence the adhesion quality, to provide a basis for optimization of the adhesion process. A simulation platform was created, to make it possible to evaluate or predict the adhesion quality of space solar cells when the dimensions of the solar cells and the adhesive were changed.
